I believe the Beta test is still going on. I looked at participating some time back and decided I didn't really care enough about streaming to participate. Rumor (only) that I have heard is end of the year. And I don't think anyone is going to give you a copy of the software, there is very specifically a confidentiality agreement the test participants must agree to.
Here is a link to the trial signup site: https://www36.verizon.com/MM/Protected/TestTrack/Signin.aspx. I have read somewhere that they are no longer accepting applications to participate, but you could try to sign up and see.
Verizon FiOS TV, Internet, and phone
Yeah I'd love to put a usb drive into my dvr and play videos that way too, except Verizon has disabled (purposely) the USB, eSATA, and FireWire ports on all their DVRs that they use, even the newer models like mine. What a joke. I want to go back to directv with Tivo. I have a 750 GB hard drive that I was using for over a year with Tivo with no problems whatsoever, and now all of a sudden It's useless just because verizon says so.
Also, with Media Manager, I am finding posts from 2007 of this feature to be available "soon" and it still isn't.
My guess is that it's coded so bad they need to completely redo it, or something like that is seriously wrong.
In other words, I doubt it will be available any time soon. It's funny, even with the current media manager, no audio will play on my DVR.
I find the song I want, press play, the status bar and timer moves, but no audio.
The problem would not be with the software itself, because Media Manager works as advertised (allows viewing of photos and streaming of audio from your PC) in my setup, so there is something specific with your setup that is causing the problem. In fact, I have the Media Manager software installed on multiple PCs on my home network, and the Multiroom DVR accesses images and audio from all of them just fine.
I'm not saying MM is perfect, as it needs LOTS of work, but right now, it does what it is advertised to do.
